RFID multiple range method and system
First Claim
1. A method for determining the range of an RFID tag from an origin, the method comprising:
- securing an RFID tag with a unique numerical identifier to an object;
transmitting the unique numerical identifier associated with the RFID tag using RF signals;
receiving the RF signals at a designated location;
reading the RF signals and determining the unique numerical identifier being transmitted by the RFID tag;
analyzing the unique numerical identifier for a corresponding identification of an object from a predetermined index;
determining whether the object was not found on the index; and
alerting a user when an object is missing.

Abstract
The present invention is a method and system for determining the range of an RFID tag from an origin using radio-frequency identification (“RFID”) tags. An RFID tag with a unique numerical identifier is secured to an object. The RFID tag transmits its unique numerical identifier using RF signals, wherein the numerical identifier further comprises an array of extensions. The strength of each of the RF signals corresponds to an extension of the array of extensions. A receiver reads the RF signals and determines the unique numerical identifier and extensions being transmitted. An information processor interconnected with the receiver analyzes the unique numerical identifier and extensions from a predetermined index, and the information processor determines the range of the identity and range of the RFID tag from an origin.
